Flow Labelled IP: Connectionless ATM Under IP

IP traffic on the Internet and private enterprise networks has been growing exponentially for some time. This growth is beginning to stress the traditional, processor based design of current day routers. Switching technology offers much higher aggregate bandwidth but presently only offers a bridging solution. Various proposals are under way to support IP routing over ATM switching technology; h...

کنترل مود لغزشی برای ازدحام در شبکه های TCP/IP

In this paper a new sliding mode controller for congestion problem in TCP networks has been proposed. Congestion occurs due to high network loads. It affects some aspects of network behavior. Congestion control prevents or reduces loads in bottlenecks and manages traffic. By using control theory, closed loop data transfer processing structure in computer networks can cope with the congestion p...

Survivable IP network design with OSPF routing

Internet protocol (IP) traffic follows rules established by routing protocols. Shortest path based protocols, such as Open Shortest Path First (OSPF), direct traffic based on arc weights assigned by the network operator. Each router computes shortest paths and creates destination tables used for routing flow on the shortest paths. If a router has multiple outgoing links on shortest paths to a g...

IP Network Designer: Interface for IP Network Simulation

In this demonstration, we present IP Network Designer: interfaces for IP network simulation. The IP Network Designer consists of two subsystems: The IP Network Design Workbench and a 3D simulator. IP Network Design Workbench is intended to support a collaborative design and simulation of an IP network by a group of network designers and their customers. This system is based on a tangible user i...

Optical Network Design with Optical Constraints in IP/WDM Networks

In this paper we consider algorithms for the logical topology design and traffic grooming problem in WDM networks with router interface constraints as well as optical constraints. The optical constraints include restricted transmission range due to optical impairments as well as limits on the number of available wavelengths. We formulate this problem as an integer linear program which is NP-com...
